Way to kill running scripts?

[Zorba]

Operating system: Windows 7
Browser version:33.0.1
32-bit or 64-bit browser?: 64

Is there a feature in PM that stops all running scripts? I get the impression that the browser is often bogged down/slow to respond due to something running in the background. Thanks

Yes, there is and in one of the latest releases it has been made automatic (it used to show a confirmation dialog in earlier versions).
If it doesn't happen soon enough you can reduce the timeout in about:config, though right now I'm not sure which setting it was so I'll defer this to more knowledgeable people.

Scripts from twitter are notorious for slowing down Pale Moon. Use a blocker (like uBlock Origin).

I think these are all the relevant config preferences.

dom.always_stop_slow_scripts
dom.max_script_run_time
dom.max_chrome_script_run_time

Thanks very much.

I've reduced these to 10 and 15 respectively. These are seconds presumably? Seems to be improved...

PS: tried 2 and 3 - big difference!

Be careful because making them too short will break functionality of websites and the browser. You should not stop chrome scripts that quickly because that governs the browser's internals and stopping those scripts prematurely will cause all sorts of trouble.

Extension KillSpinners (CAA: killspinners@byo.co.il.xpi).
or CustomButtons button:

Code: Select all

function  allStop3() {
   let visTabs = gBrowser.visibleTabs;
       visTabs.forEach( tab => {
         let browser = gBrowser.getBrowserForTab(tab);
             browser.stop();
             browser.webNavigation.stop(2);
         })
 }

Is this comment regarding "10 and 15" or "2 and 3" above?

Yes.

10/15 may fail on older hardware.
2/3 almost guaranteed to cause issues.

In general you should always leave the "chrome" setting alone. Only "content" matters.
